Bearing cage with pockets having radial storage holes

Abstract

A cage is for a bearing including an inner body having an inner raceway surface, an outer body disposed about the inner body so as to define an annular space, the outer body having an outer raceway surface, and a plurality of rolling elements disposed within the annular space and rollable simultaneously upon the inner raceway surface and the outer raceway surface. The cage includes an annular body disposeable within the annular space between the inner body and the outer body, having a centerline and including a plurality of pockets spaced circumferentially about the centerline. Each pocket is defined by a separate radial surface and is configured to retain a separate one of the plurality of rolling elements. At least one radial hole intersects the radial surface of one of the plurality of pockets and provides a storage space for lubricant.
